Highway 2 from Monroe to Gold Bar in Washington State sucks at night.
The range of light 'temperature' between vehicles is amazing... Some are clearly not street legal.
Not to mention 'brightness' or alignment.
I'm an advocate of vehicle safety inspections.
A 25 point check list that if you fail any no new registration. At a minimum the guys headlights are pointing at the road and not the trees...
And you can also rest assured at the next light as he's stopping his brakes work.
